IMPROVED BEIRIGERATOR AND SIDEBOARD.

Be it known that I, JQHNATHOMPSON, of the city vo't Auburn, in th'e county of Cayuga, and State ot' New York, have invented a new and useful Improvement on'Refrigerators and Sideboards combined; and I do declare that the fbllowin'g is a full, clear, and enact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1 is a perspective view of the sideboard.

Figure 2, a perspective view ofthe refrigerator. Figure 3 is a sectional view of the refrigerator. Figure 4, a section of angular post. A Figure 5 is an interior view. Y

.A, in iig. l, is the ice-box; B B, air-tight compartments; C C, provision-chambers; DD, ventilators; E, faucet; F, section of inside lining, cut so as to admit the stucco or concrete filling; G external covering; GJ, inner wall,l of same material as external; K, ribs or anchors to x filling to walls; H, concrete-llcd space;`I, l air-space; J, inmost lining.

i Fig. 4. L, a-section of angular post, cap, or sill. i I`construct my refrigerator and sideboard by first making a frame of suitable wood, sawing myposts, i sills, and caps, in angular form, as represented in section, ig. 4, at L. These are framed together, and tied by grths of hoop-iron, or strips of thin wood, extending from sill to cap, and from post to post, attached by screws, nails, or dove-tailed, linsh with outer face of frame. The edges of these should be bevelled,vsame as ribs K, to hold the concrete. I now cover this frame with a board, manufactured similar to trunk-boards, or first providing a web of strong cloth, woven open, from manille, or other strong and cheap suitable material, one side being covered with any suitable pulp, or bystrong paper, adhered to its surface by means of a water-proof size, and pressed,so as to furnish a smooth face or finish, or at the same time, by means of dies, medallion or embossed, 'gnres, mouldings, and ornamental designs, may be-placed upon its panels. This material is cut to size, and glued, pasted, and nailed irm to the outer edges of the posts, caps, sills, and door-frame. A lighter but similar material is nailed on the inner angle ofthe frame.- This is also adhered to the posts, sills, and caps by adhesive water-proof paste or glue,.and nailed. I

The space between the outer and inner wall I till with a concrete, composed of plaster of Paris or gypsum, with its water of -crystallization'driven oi, and granulated charcoal, from hard wood or anthracite coal, broken, so as to pass an eighth-inch-mesh sieve. These are mixed in about equal quantities when dry, and water is then added, so as to run readily, and {ill the space by injection throughthe cuts marked F. The ribs K are 1 nailed to the inner face of these walls, so as to bindV the concrete and walls iirm together, after filling. An .inner wall is nailed to strips one-quarter inch thick, and the whole is nailed and adhered to the i'nner Wall and frame'by nails, glue, and paste, so as to` form an air-chamber. This may be of trunk-board or web of cloth, :finished water-proof on the.inside by paste, glue, seedlac, or shellac, and painted with graphite, or finely-ground anthracite coal, or a -metal lining instead, as preferred. The-air-'space at bottom should be covered by board, lor corked, so a stratum of the concrete may be placed on the bottom; and a iinal covering of thin boards, '-attached'by screwsor nails to the sills, closes all. Y

Therdoor :indice-chamber openings are enclosed by nailing lining to their posts, with glue or paste between,4 The doors are made of thin-narrow strips, framed together at their corners, anda surrounding of leather, or felt., or other suitable material, is glued onfits face, and passed loosely around its edge, and glued upon its opposite face. Over this, an ornamented covering of the same material as the outer wall is nailed, and glued to the sides, and the space filled with concrete. At this'stage,4 the whole is perfectly dried, its surface smoothed, painted, or japanned, so as to render all water-proof. The outside is now nished by suitable ornamental mouldings from wood, oiled, varnished, or painted, so as to harmonize with the nish of the room. f

The base-moulding drops, so as to exclude a *view of the board bottom. The inouldings should be attached by ornamental screws, cast, or are made fast by a corner-box of sheet or cast metal, encasing the corners of lower mouldings, or may be attached to the board bottom and base.

I constructL two air-tight compartments, one on each side of the ice-box. These compartments, B B, are enclosed, so as to be freed from Iall odor from provisions in chambers C C, or from moisture. The cold air circulates around them, and reduces'the temperature, by conduction of the heat. Y y

These chambers are provided with doors, closing on packing, air-tight, bjr means of an air-cock, entering the box. I

The air can be displaced by an air-pump, and choice fruits or perishable articles preserved for use at pleasure. i

Ice-box A extends to the bottom of the refrigerator, and is provided with a strong wire or wood rack on sides and bottom, as seen at O, into which the ice majr be dropped. Beneath the bottom of this rack, apertures m m pass through the sides, and enter the enclosed conductors n n, and are let into the provision-chamber CC near the top. These conductors aresoldered at their bottom and Asides tight to walls of the ice-box. The air passes into the ice-box, and down to apertures m m, up through conductors n n, out at top of chambers C C, do'wn, andout at. ventilators atfbottom of doors D D. v

Fig. 1 shows a sideboard, which may be used in combination orl separate fromthe refrigerator, being constructed of the same materials, and in the same manner as the refrigerator, omitting the ice-box and metal lining, thus furnishing a dryand suitable cabinet for the keeping of linens and other choice goods, free from mould, or the ravages of vermin.

AHaving thus described myinvention, what I claim, is-- The-construction of refrigerators and household-preserratories of angle-wood, skeleton-frames, with their entire walls of trunklboard, or its equivalent, illed with a concrete of plaster of Paris and granulated carbon, or other suitable material securing the same effects, alll asspecied and set forth.

, In testimony that I claim the foregoing, I hereunto aiiir my signature, iu presence of- JOHN A. THQMPSON Witnesses:
